> If you think about it, consciousness is not physical. My thoughts have no mass.

Could you (or anyone else who knows the meaning of "physicalism") come up with a clear definition of what "physical" means for you? Each time I read something suggesting that consciousness might not be physical I completely lost track of the meaning, a bit like when I read that some experience (or chemical!) is not "natural".

Certainly, it has nothing to do with mass or energy (or you would merely postulate the existence of some new particle with this and that properties). It certainly does not mean, either, that it is not composed of matter (like for instance sound or temperature), or you would have said "immaterial".

Maybe that's because of those years spent studying physics, but I just can't get what could exist but still not be physical (or natural) as for me those are equivalent.
